Funny you should mention that - within the last half-hour I have come up with
(for header checks file):-

if /^From:.*amazon\.co\.uk/             
!/\<.*\@.*amazon\.co\.uk\>/     WARN Fake Amazon address
endif

Completely untested - it would be interesting to know if I am getting my regexp
syntax right.  :-)

Not quite what you wanted - but hope it helps.
